Need to disassemble my TJ-25

[tallaz]

I need to disassemble my TJ-25 to swap the top layer of the screen for one that is in better condition. Does anyone know if I need to buy some special type of screwdriver to remove these abnormal type of screws?

I just bought (and used) a Tri-Wing Size #00 screwdriver from http://www.lara.com/ but I've seen them in other places too.

They are advertized to work on the GameBoy. Try this google search http://www.google.com/search?hl=en&rls=GGLC,GGLC:1969-53,GGLC:en&q=tri+wing+screwdriver&spell=1
